To all w/tom it may concern.-

Be it known that we, GEORGE WILLIAM TROMMLITZ and JAMES MONROE GIBBs, citizens of the United States of America, residing at Denver, in the State of Colorado,

county of Arapahoe and have invented certain new and useful Improvements in Gripping Connections for Inflation-Valves; and we do declare the following to be af ull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the thereon, which form a part tion.

Our invention relates to figures of reference marked of this specificaan improved device for making quick-connection with infla- Heretofore, so far as we are has only been made g, making the opand tedious.

to overcome this difficulty; the invention consists of the features hereinafter described and claimed,

all of which will be fully understood by reference to the accompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure improved device in use.

f rubber or other This ring surrounds the nipple extremity 6 of the plunger. The nipple 6 enters the outer extremity of the casing 9 (see Fig. l) of the inflation-valve 'mounted on the rim of the bicycle-wheel 10 or other wheel or device to be inflated.

Fulcrumed on the casing 5, as shown at 12, are two lever-like members 13, provided with interiorly threaded cooperating jaws 13, adapted to automatically grip the exteriorlythreaded extremity of the valve-casing 9 by virtue of two springs 13, respectively connected with the members 13 and bearing against the casing 5 in the rear of the fulcrum 12. As shown in the drawings, the springs 13 are integral with the members 13 and formed by cutting around an elongated portion of each member, leaving it intact at one extremity and pressing the parts inwardly sufficiently to engage the casing 5, whereby the jaws 13 of the members are normally held in the closed position. These jaws are curved to fit the cylindrical extremity of the valvecasing 9.

To the rear protruding extremity 6 of the plunger 6 is attached the tube or air-conduit 14, connected with the nipple 15 of an airsupply source. This tube 14 may be connected with an air-pump (not shown) or with a source of compressed air, as may be desired.

To use our improved device, it is only necessary to press inwardly on the rear extremities of the members 13 until the jaws 13 are sufficiently open to allow the outer extremity of the valve-casing 9 to pass between them. The nipple end 6 of the tube 6 is then inserted in the open end of the valve-casing until the packing-ring S is pressed tightly against said casing,forming an air-tight joint.

When the device is applied, the spring 7 holds the plunger tightly against the end of the valve-casing and prevents the plunger from moving rearwardlyin the casing 5.

Having thus described our invention, what we claim is-- 1. A connection for inflation-valves, comprising spring-actuated, lever-like grippingjaws, a support on which the jaws are fulcrumed, and a spring-held tubular plunger carried by the support, one end being fashioned to engage the extremity of the inflationare fulcrumed, and a hollow plunger carried by said support and protruding between said jaws, the said plunger extremity being adapted to enter the open end of a valve-casing, and a packing-ring surrounding the extremity of the plungerto form an air-tight joint.

4. The combination of two cooperating, le-

ver-like members, a tubular casing on which 7 said members are being provided with jaws at one extremity adapted to grip the casingof a valve, and arms at the opposite extremity, springs engaging said arms whereby the jaws are held normally closed, and a spring-held hollow plunger located in the tubular casing and protruding at both extremities.

5. The combination of a tubular casing, a plunger passing therethrough, a coil-spring located within the casing and surrounding the plunger, one extremity bearing against a shoulder on the casing and the other extremity against a shoulder on the plunger, and spring-actuated lever-like jaws fulcrumed on the tubular casing.

In testimony whereof we affix our signatures in presence of two witnesses.
